Study on Router Buffer Size with NewReno Congestion Control Method
Jianping Wu · Dianzi xuebao · 2009
The problem of router buffer size is one of the hotspots in recent router research.Existing research focuses on traffic pattern,network topology and configuration,router architecture and configuration,network dynamic and performance evaluation criterion.Based on the existing study on evaluation criterion and traffic pattern,this paper proposes a new evaluation criterion named Flow-Completion Time Ratio,which does not rely on the network property.Based on this criterion,we perform simulations using self-similar traffic as traffic pattern.Observing SFCTR,AFCTR and FCU,we conclude that too large and too small buffer size will both degrade the network performance.We also provide reasonable method of setting router buffer size.
